This paper is the second 1 in which the results of experiments having a two-fold object are presented. The experiments were made to determine (1) the action of several of the more frequently used antiseptics on some of the more common pathogenic organisms and (2) the reliability of the present standard of evaluating antiseptics as a means of correct appraisal of their practical value. A more detailed report may be expected in a later communication.
In May, 1927, Leonard and Feirer2 described a new antiseptic known as S.T. 37. It is a practically colorless, odorless, limpid fluid with a warm, sweetish taste, containing 1 mg. of crystalline hexylresorcinol per cubic centimeter of solvent, consisting of 30 per cent glycerin and 70 per cent water.
